Compare water reclamation, greywater use, and desalination.

Answer:

Water reclamation is a process that is used to rid wastewater of solid material and impurities. This wastewater typically contains sewage. Biological and chemical processes are used to treat the water. In the process of water reclamation, water is returned to a usable state, but not a potable one. Greywater is water that does not contain sewage. This water can be collected from institutions that have separate collection processes for sewage and other wastewater. This water can be used directly for some purposes or can undergo treatment for use in agriculture and other applications. Desalination involves removing dissolved minerals from water to make it drinkable. This process is expensive, requires a great deal of energy, and can be detrimental to the environment in certain circumstances. In areas where freshwater is scarce, but saltwater is not, this is a viable option.
